Inspection Device For Department of Energy Hanford Site Underground Tanks
Objectives
Conceptual Design Requirements
• Leakage of the radioactive material
into ground is a major concern due to
environmental impact
• The Columbia River is located five
miles from the Hanford Site
• It is a extremely important to avoid
impacting the ecosystem and also avoid
contaminating the water provided to the
major cities
• The objective is to design and built a
robotic inspection device
• It will travel through the refractory pad
cooling channels to gain further
knowledge of the condition of the tank
and the source of leakage
Problem Statement
Jennifer Arniella
Gabriela Vazquez
Daniel Giraldo
Advisors: Mr. Dennis Washenfelder
Dr. Benjamin Boesl
Dr. Dwayne McDaniel
Mr. Tomas Pribanic
Motivation
High level radioactive waste has
leaked from underground tanks
located at Department of Energy
Hanford Site in Washington State.
Timeline
• Deployed through riser to annulus floor
• Travel through 1.5 x 1.5-in channel
• Navigate through four 90° turns
• Remote controlled
• Provides video feedback
• Radiation tolerant at 85 Rad/hr
• Withstand high temperatures (170 °F)
• Device must not subject the channel walls to pressures
greater than 200 psi
• Fiber optic line supplies power to motor and camera as
well as means of retrieval in case of malfunction
Major Components:
Dimensions:
1.2-in wide by 1.21-in long by 1.15-in height
• Treaded Tracks
• Camera
• 8 Gears
• Tether
• 2 Motors
• Magnetic plate
• Frame
• 4 wheels
